fh2wheel — Racing Wheel + Real Force Feedback

### Changed - New look for `fh2wheel-config.exe`: dark theme and a **Live preview** panel with a wheel that turns with yours, the pedals, the engaged gear and the Xbox buttons lighting up as you press them. ### Fixed - `fh2wheel-config.exe` releases the wheel after each force test instead of keeping it until it is closed. Upgrade: replace `D3DCOMPILER_47.dll`, `fh2wheel.dll` and `fh2wheel-config.exe` next to `azimuth.exe`. Your `data\fh2wheel.ini` is kept.

### Added - Handbrake support. The game has no handbrake axis for wheels, so pulling the handbrake past 30 % presses **B**, the game's handbrake button with a wheel (A is the clutch). Another button can be set with `HandbrakeButton` under `[Axes]` in `data\fh2wheel.ini`. - A USB handbrake can be its own device: new **Handbrake** list in `fh2wheel-config.exe` (`HandbrakeVid`/`HandbrakePid` in `[Devices]`). - The trace log shows the handbrake value. ### Changed - Device lists in `fh2wheel-config.exe`: **Wheel** only shows force feedback devices, and a device chosen in one list is hidden from the others. Pedals or a handbrake set to the wheel's own device become "None" and their axes are read from the wheel. Upgrade: replace `D3DCOMPILER_47.dll`, `fh2wheel.dll` and `fh2wheel-config.exe` next to `azimuth.exe`. Your `data\fh2wheel.ini` is kept; run `fh2wheel-config.exe` to set up a handbrake (Detect on the **Handbrake** axis row).
